3. Personality and behavior problems
Patients with Alzheimer’s suffer from disturbances in their personality, mood, and behavior. They tend to withdraw from the community, family, and close friends. They may suffer from hallucinations (seeing and hearing things that don’t exist) and delusions (believing in untrue things). They may be uninterested in their usually enjoying activities. They may become depressed, apathetic, aggressive, irritable, and more worried than before. Also, they may be compulsive or obsessive. They may lose their trust in others. They also may have disturbances in their sleep habits.
